To all whom it may concern." I

Belt known that I, ALBERT Asrnn, citizen ofthe United States, residing at ParshalL; in the-county of Mountrail and State of North Dakota, have invented certain new and useful Improvements in Tractor CQ11- trol Attachments; andI do declare the following to be a full, clear, and exact description' of the invention, such as, will enable others skilled in the art to which it appertains to make and use the same,- reference being had to the accompanying drawings,'and to the letters andfigures'of refer-v ence marked thereon, which form a part this specification. I

My invention relates to tractor Conn-ointachments connecting a tractor to ,a binder or other agricultural or 'farn'i implement by which the tractor 'is guided by; suitable means within reach of the operator seated on the farm implement, and the-supplypf fuel to the engine and the sparking device of the engine are likewise-.iin'der controlfo'f the operator seated on the farm'implement The invention has for itsvobj'e ct to pro-- vide a constructionin which the parts of the attachment can be readilyconnect'ed in a practical way. to the tractor and the farm implement, and provision'be madefor extension and contraction of the steering conn ection-betweenthe tractor and tarm implement inmaking turns, and also for automatically taking up slack [in the cables through which the fuel supply andthe spark attachments illustrated in Figure 1, andv showing part of a seed-drill substituted for the binder ofFigure 1; Figure is an enlarged: sectional detail of parts of theattachment connected to the tractor; I I Figure 'i r-is an enlarged detail of parts of the attachment connected to the binder;

Th'efconnecting rod 13 may,

be sustained and guided byan intermediate bracket Qthroughan opening-25in which the rodwill freely turn, this bracketguide being connected to an arm 26 connected to the farm implement, or being otherwise supi r e 1 a I A forked lever is fulcrumed to suitable support, gay to the saddle 10, and its I dle 36 alongside the sheave 35.

'open face of sheave 35 is closed by a plate long arm 28 is connected by a link 29 to a ball-socket casting 30 connected by a clip 31, or otherwise, to the lever 32 which connects with the throttle that controls the supply and cut-off of fuel of the engine. One of the short arms 33 of this lever 27 is connected by a flexible cable 34 to a sheave 35 loosely mounted on a shaft or spindle 36, and the other short arm of the lever is connected by another flexible cable 37 to a sheave 38 also loosely mounted on the spin- The outer 39'held in a fixed position to the spindle 36 by a set screw 40, and the outer open face of the sheave 38 is closed by a side wall of bracket 19 against which it fits. The sheave 35 contains aspiral spring 41 one end of which is attached by a pin 42 to the fixed face plate 39 and the other end to the sheave. The other sheave 38' contains a spiral spring 43 one-end of which is attached by a end to the sheave. The springs are so placed in their respective sheaves that when one cable is slacked'on the side towards which the tractor is turned the slack is taken up by the spring turning the sheave in the direction to wind -up the cable, and when the tractor is turned in the opposite direction' the slack in the cable on that side will be taken up. In the manner described the slack in the two cables is automatically taken up and the cables thus always maintained taut. When it is desired to throw the throttle lever to supply or cut-off thesupply of fuel to the engine the proper sheave is turned, to pull on the cable leading to the short fork of the throttle lever which will sheaves constitute a slack'takeup for the two cables in turning thetractor and also in shifting the throttle lever. One of the cables passes through an opening 46 infthe guide-plate 'or bracket 24, and the other through an opening 47 in the same guideplate and by this means the cables are supported between their opposite ends.

Two other sheaves 48 and 49 formed and supported as and in the manner described for sheaves 35 and 38 and therefore not requiring further detailed description, are connected one by a cable 50 to one short arm of a'forked lever 51 and the other 52 to the other short arm of said lever, the long arm 53 of said lever being connected to a link or lever 54 which will connect with the I pin 44' to the sidewall of bracket 19 and the other To facilitate the'turning of the through a lever 57 which is connectedby a,

cable 58 that passes through an opening 59 in the guide-bracket 24- and. at its other end passes through an opening 59 and then fastened to the notched arm from the bracket 19. V 1

In Figure 2 of the drawing I have shown the same attachment as that described for Figure 1 used in a seed drill instead of in connection with a binder. The seed drill is indicated in a general way by the numeral 61 and-will be coupled in any suitable manner to the tractor. The bracket 19 which carries the sheaves 35, 38, 48 and 49 will be 60 extending supported from one side or the other of y the drill as occasion or necessity may 'require in any suitable manner, The saddle which carries the spindle of the pinion that meshes with the steering post gear and other features described for Figure 1 will be attached and operate i'n the same manner as described for the binder. In the case of the seed drill however the steeing rod 14 may have the coupling knuckle 16 changed nearer to the steering wheel 18.

I have illustrated and described with particularity the preferred details of construction but changes can be made therein and essential features retained.

The control attachment can be readily applied to different types of tractors and farm implements already in use; and the various parts can be made at comparatively little cost, and when applied serve in a very efficient manner the purposes for which designed.

It will be observed that the throttle that controls the supply of fuel to the motor, and

possible for both the fuel supply and sparking device to be operated as one or the other may be selected;

Having described my invention and set forth its merits what I claim is 2' 1. An attachment for a tractor and farm implement, comprising a lever and means ing saidlever, and slack take-ups connected one with each cable and operating to takeup slack in the cable. I

2. An attachment for a tractor and farm implement, comprising a pair of levers, means for connecting one lever with the throttle of the tractor, means for connecting the other lever with the sparking-device of the tractor, and a slack take-up connected with the cables of both leversand operating to take-up the slack in the cable of each lever.

3. An attachment for a tractor and farm implement, comprising a lever and means for connecting it with an operative controlpart of the tractor-motor, a pair'of spring tension sheaves supported from a part of the farm implement, and a cable leading from each sheave to said lever, each sheave serving to take-up slack in the cable connected thereto. a

4. An attachment for a tractor and farm implement, comprising a pair of levers, one having means for connecting it with the throttle of the tractor and the other means for connecting it with the sparking-device, two sets of spring-tension sheaves, a bracket in which said sheaves are supported, said bracket being connected with a part of the farm implement, and cables leading from each sheave of the two sets of sheaves, the cables from one set of sheaves. being connected with one of said levers and the cables of the other set with the other lever, said sheaves serving as slack take-up in the cables leading to the two levers.

5. An attachment for a tractor and farm implement, comprising a forked lever fulcrumed to a part of the tractor, alink connected with one arm of said lever, a universal joint coupling between the other end of said link and a throttle lever, a cable I extending from each' of two other arms of the forked-lever, a pair of spring-tension slack take-up sheaves each of which has one of said cables :connected thereto, and a a
